Terrible service and lack of customer empathy

On Saturday I went to Maponya Mall Debonaires. I placed my order and left to Burger King cause I know they take decades to prepare the pizza's. Came back and still waited, finally I get my orders .. when I checked it's wrong .. by then O already requested for an Uber .. I report to the lady that gave me my food .. she went to the cashier .. I asked her for the proof of Payment and responded saying that she threw it away however she saw my order it was indeed to small pizza's .. one with single cheese and the one with double cheese .. the lady said to me please wait for another 5 minutes whilst wr fix it .. I said to her I can't cause I already requested for an Uber .. she didn't have a solution and looked at the on duty manager that guy didn't even bother to speak to me .. he was listening to the conversation but couldn't be bothered. I left to go order from another restaurant cause he was not interested to help or even look at me. What kind of service is that guys .. was I going to receive such treatment if I was off a different race? I was going to receive such treatment if I was in Sandton? I'm disgusted by the poor service and ignorance. I already stomached the fact that we wait for a good 20 to 30 minutes for our food .. no operational efficiencies whatsoever
